93674 - QUANTITATIVE ECONOMICS AND PUBLIC POLICY

Conoscenze e abilità da conseguire

The course provides an overview of some of the most widely used quantitative methods for social sciences and economics, with an emphasis on regression analysis. The general linear regression model is considered at length, together with some of its incarnations and extensions. These include: the instrumental variables method, models for discrete random variables, models for panel data, and models for time series data. The course has an applied orientation. Examples draw heavily from the political sciences, and are analyzed using the R programming language. At the end of the course, diligent students will be able to apply the methods considered, using R, and to correctly interpret the results of their analyses.

Contenuti

The purpose of this course is to learn some the foundations of statistics and, while doing that, to familiarize oneself with the Stata software and programming language.

Modalità di verifica e valutazione dell'apprendimento

Students will have to complete a project using Stata, that will count as a midterm exam. A "pass" grade can be refused, and the final exam retaken, ONLY ONCE. The grade on the Stata project can't be refused.

The final grade will be a weighted average of the result of the midterm exam (Stata Project) and of the final exam, with respective weights 0.4 and 0.6.

The deadline for the Project is Friday 15 December 2023, at 11:59 pm.
